The Democratic sponsor of climate change legislation says he is working to address Republican concerns that led him to delay the bill's introduction.
Sen. John Kerry of Massachusetts says Republican Sen. Lindsey Graham of South Carolina, Senate Democratic leader Harry Reid and others are discussing how to revive the climate bill.
Kerry postponed the bill Saturday after Graham threatened to withhold support if Reid pushes ahead first with an immigration bill.
Kerry said independent Sen. Joe Lieberman of Connecticut as well as their other colleagues are looking for a solution and acting in good faith.
